AI filmmaking: how to make a film with AI
AI filmmaking means making a film where the shots are generated by AI video models instead of filmed. You still write it, direct it and edit it. What changes is the cost: a shot takes a few dollars and a few minutes. This is how it works, written by the VFX team that builds Root, and what an AI filmmaker actually does day to day.

How a film gets made with AI
1. Break the script into shots
An AI video model makes one shot at a time, a few seconds to half a minute long. So the first job is the one it's always been: decide what each shot is, how long it runs and where the camera sits.2. Design the characters and locations
Make a character sheet and the key locations as still images first. These become the references every later shot is built from, and they're the main reason a character still looks like themselves in shot forty.3. Generate the shots
Pick a video model for each shot. Some are better at people, some at motion, some at long takes. Feed in the references, generate a few takes, and keep the best one.4. Fix what's almost right
Re-frame a still from a new camera angle, relight a shot to match the one before it, or swap in a different character and keep the performance. This is the part that feels most like VFX work.5. Add voices, lipsync and music
Generate dialogue in a chosen voice, sync the lips to it, and score the scene. Bad sound is often what gives AI work away.6. Edit and finish
Cut the takes on a timeline, upscale, convert to HDR if you need it, and export.
What AI filmmaking costs
You pay per shot. Here is what one five-second shot at 720p with sound costs on Root, on four models filmmakers use a lot:
| Model | Good for | Longest clip | One 5 s shot, 720p |
|---|---|---|---|
| Seedance 2.5 | Long takes, many references | 30 s | $1.99 |
| Kling 3.0 | Realistic motion | 10 s | $0.73 |
| Kling Omni | Several references in one shot | 15 s | $0.65 |
| Seedance 2.0 Mini | Drafts with references | 15 s | $0.65 |
A one-minute film is roughly 12 shots. On Seedance 2.5 that's about $23.88 if every shot works first time, and about $71.64 with 3 takes a shot, which is closer to real life. Drafting on a cheaper model first brings it down.
AI filmmaking tools in Root
- Video models side by side, including Seedance, Kling, Veo, Runway and Luma, with the price shown before every run.
- Projects organized into sequences, shots and takes, with approvals your team can see.
- Reference images and trained character models to keep a cast consistent.
- Photo to 3D model and a 3D scene for blocking out shots.
- Re-angling stills, and relighting and character replacement on shots you already have.
- Voices, lipsync and music.
- A timeline to cut it all together, with upscaling and HDR on the way out.
- A record of every creative decision, exportable as an authorship dossier.
- The same tools from Claude or ChatGPT, or the Root API.
Who makes Root
We're a VFX studio. We worked on The Bear, The Creator and the Aflac duck, and when AI video arrived we did what everyone did: opened twenty tabs, paid for six subscriptions, and lost track of which version of a shot was the good one.
Root is what we built to stop that. One place, every model, and the shots kept in order like a real production.
What we got wrong first
Our first mistake was prompting each shot from scratch. The character's face changed between cuts, and we'd spend the afternoon regenerating rather than directing.
What fixed it was boring: build the character once as a reference sheet, give that same image to every shot, and for anyone who recurs, train a model on them.
The second thing we learned is that some video models refuse a human face they can't trace back to a source, even one you generated yourself. It stops a shot dead and the error doesn't explain itself. We built the way around it into Root, and there are tutorials that walk you through it.
AI filmmaking questions
What is AI filmmaking?
AI filmmaking is making films where some or all of the shots are generated by AI models instead of being filmed. The filmmaker still writes, directs, chooses the takes and edits. The AI does the job of the camera and the set.
Can I use AI to make a film?
Yes. People are making short films, music videos, ads and trailers this way now. You build the film shot by shot, keep characters consistent with reference images, then edit and add sound as you would with any other footage.
How much does AI filmmaking cost?
On Root, a five-second Seedance 2.5 shot at 720p with sound costs $1.99, so a one-minute film of 12 shots is about $23.88 if every shot works first time. They don't, so budget for 3 takes a shot: about $71.64. Cheaper models such as Kling Omni or Seedance 2.0 Mini bring that down a lot.
How do you keep a character consistent in AI video?
Design the character once as a reference sheet and give that image to every shot. Models such as Seedance 2.5 and Kling Omni take several references at once, so the face, the costume and the location can all go in together. For a recurring character you can also train a model on them.
Will AI replace filmmakers?
We don't think so. We run a VFX studio, and AI has changed how we make shots, not who decides what the shot should be. People still decide the story and make the edit. AI mostly makes each shot cheaper.
How do I become an AI filmmaker?
Make something short. A 30-second piece with one character and two locations teaches you most of it: breaking a scene into shots, keeping a face consistent, choosing between takes and cutting to sound. Then make it again, better. Knowing how films are shot and edited still matters more than knowing the tools.
Can AI-generated films be copyrighted?
The U.S. Copyright Office's position is that purely AI-generated material can't be protected, but a person's creative selection, arrangement and changes can be. That makes a record of your decisions valuable. Root keeps one for every project and can export it as an authorship dossier.
What do I need to start?
An idea you can break into shots, and a tool that lets you manage many shots and takes. You don't need a camera, a crew or a powerful computer. Everything runs in the browser.
